Chrysoprase and Fayalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Fayalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Fayalite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 4.392 whereas that of Fayalite is 4.392.
